A series of planned visits to the U.S. by prominent Arab Gulf personalities appears to be aimed at laying the groundwork for a major U.S.-Gulf summit in May.

According to high-level Arab officials, the sought-for summit is mainly intended to resolve a months-long political crisis pitting Qatar against a four-nation Arab bloc led by Saudi Arabia.

Saudi Crown Prince Mohammad bin Salman is scheduled to travel to Washington on March 19. The following month, Qatari Emir Tamim bin Hamad Al Thani is also expected to pay a visit to the U.S. capital.

Speaking on state television late Wednesday, Kuwaiti Deputy Foreign Minister Khaled al-Jarallah said the visits were intended to pave the way for the summit.

"There is hope of convening a summit in the U.S. with the aim of resolving the crisis in inter-Arab relations," al-Jarallah said. "But invitations have yet to be sent."

"This crisis must be resolved one way or another so that we [Arab States] can collectively deal with the many challenges facing the region," he added.

"The U.S. is aware of this and -- like Kuwait -- hopes to end the dispute so that it might devote itself entirely to confronting these challenges," al-Jarallah said.

This week, Timothy Lenderking, U.S. deputy assistant secretary of state for Gulf affairs, along with retired U.S. Marine Corps General Anthony Zinni, conducted a whirlwind regional tour that took them to Kuwait, Qatar, Egypt, Saudi Arabia, Bahrain and Oman.

The tour was reportedly aimed at finding a solution to the Gulf crisis and laying the groundwork for a summit to be held sometime in May.

Last summer, a Saudi-led bloc of states -- including the United Arab Emirates, Egypt and Bahrain -- collectively severed relations with Qatar, accusing Doha of supporting terrorist groups in the region.

The four-nation bloc threatened to impose further sanctions on Qatar if the latter failed to comply with a long list of demands, including the closure of Doha-based broadcaster Al Jazeera.

Qatar, however, has steadfastly refused to comply, strenuously denying the accusations leveled against it.

Kuwait, for its part, has maintained neutrality, dispatching several high-level emissaries to mediate between Qatar and the countries arrayed against it.
